| Popis: | We report results of an investigation of a lamp for spectral calibration that is based upon molecular fluorescence. An argon ion laser is used to excite the B state of molecular iodine and the resulting fluorescence provides a series of lines that cover the wavelength range 515 nm to 1 340 nm. The intensities of the lines are fixed with respect to one another and are appropriate for determining the relative spectral responsivity of an optical instrument. We discuss a specific example that demonstrates the salient features of this lamp. |
